LTM Clustering

Hi   I am working on DC DR solution. I was just thinking whether can we have multiple LTMs in single cluster like.. the Primary DC will have 2 x LTMs and the DR DC will have one LTM. Can I cluster...

    You sure can. We do exactly that. You will need to create a sync-failover device group with all the LTMs in it. Look at the Redundant System Configuration Guide, and in particular the section on device groups.

     

    As with an HA pair, you need layer 2 connectivity between all the LTMs.

You do need to be running v11 or later though. v10 and earlier were strictly 2 node HA (active/active or more usually active/standby).
